BACKGROUND OF THE INVENTION Field of the Invention

This invention relates to a novel and unique method of the in store addition of vitamins and other enhancers to pet food kibbles and a device to accomplish such method.

Description of the Prior Art

Dry, cereal based pet foods became popular during World War II when tin rationing curtailed the sale of canned dog food. The manufacturing process for making cereal based dry pet food, as described in U.S. Pat. No. 8,647,690, Process for Making Pet Food, issued to Patrick Corrigan, consists of blending dry ingredients such as animal fats and meals with soy, corn or wheat grains together with vitamins and minerals, pursuant to a specific recipe, compounded, to form a dough which is then sent through an extruder. In the United States, commercial preparation of pet food exceeds 12 tons per hour and is done in such a way that each batch is nutritionally and flavor wise identical to every other batch. Pet Food Manufacture, Wendy C. Brooks DVM, DABVP, on line at VeterinaryPartner.com.

Within the extruder, the dry ingredients are moistened, heated and then forced through dies to form kibbles. The heat in the extrusion process destroys most, if not all, of the naturally occurring vitamins, proteins and other enhancers present in the dry ingredients. To counteract the loss in nutritional value which occurs during extrusion and sometimes to add other beneficial ingredients such as palatants (flavor) or compounds directed at specific pet needs such as fatty acids including Omega 3 Fatty Acids as well as Glucosamine and Chondrotin directed at hip and joint inflamation; vitamins/proteins to promote growth, increase activity or decrease weight; or, Omega 6 Fatty Acids and vitamins to promote shiny coats (ingredients referred to as enhancers in this application) are injected/sprayed onto the dried kibbles following the extrusion process. For example, in U.S. Pat. No. 8,647,690 and US Patent Application Number 2010/0080897, Frederick H. Flesser, Continuous Coating of Pellets, kibbles are placed onto a vibrating conveyor belt where they are sprayed with the desired enhancers. Following the addition of the enhancers along with the required drying, the pet food is bagged and shipped to a retailer where it is place on a shelf awaiting sale.

The entire process described above takes place at a manufacturing facility, the design of which is to maximize production while simultaneously minimizing cost. What this means is that large quantities of pet food with identical nutritional profiles which meet the general needs of the largest population of pets, are produced. There is no pet food produced which is designed to meet the specific nutritional requirements of a single pet owner. Additionally, it is generally known in the food industry that fresher is better. A strawberry picked from your garden is better than one obtained from the local farmer's market which is better than one purchased from a grocery store. From the moment the pet food is produced and during the entire time the bag of pet food sits on a shelf waiting to be sold, there is a degradation in the post extrusion enhancement that took place at the manufacturer.

SUMMARY OF THE INVENTION

It is, therefore, an object of the present invention to provide a method and a device for allowing consumers to customize pet food for the specific nutritional needs of a specific pet with flavoring, vitamins, proteins and other enhancers. It is a further object of this invention to provide a method whereby consumers can input specific nutritional needs directly to the enhancement device using electronic communications such as the Internet. Other objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as the basis for the claims and as a basis for teaching one skilled in the art how to make and/or use the invention.

The Enhancement Device of the present invention, as depicted in FIG. 1 , will comprises a liquid mixing container [1], a digital scale [2], and a tumbler [3]. While FIG. 1 depicts a digital scale [2], the digital scale can be replaced with any common analog scale without effecting the efficiency of the device. Also shown in FIG. 1 is a communication port [4] which allows the Enhancement Device to communicate electronically with consumers through computer networks such as the Internet. The Internet consists of a large numbers of computers and computer networks which are connected through communication links. A user on the Internet can access specific web pages using that web page's URL, Uniform Resource Locator. With the Enhancement Device of the present invention, the communications port [4] will allow customers using their computer or other communications device such as smart phone (via web browser or app) to access the specific web page associated with the Enhancement Device and input identifying information of the customer along with the specific nutritional needs of the customer's pet. Contained within the Enhancement Device is a EDIS, Enhancement Device Information Storage system for storing the customer's identifying information along with the pets nutritional needs. Once the information is received by the EDIS, an order fulfillment component OFC, uses the stored information to determine the type and quantity of enhancers to be added to the kibbles.

Depicted in FIG. 2 is the tumbler [3] used to mix the kibbles with the enhancers. The tumbler [3] depicted is circular in shape and includes a means for rotating the tumbler [3] to sufficiently mix the kibbles with the desired enhancers, as well as a means for tilting the tumbler [3] once mixing has been completed. FIG. 2 illustrates the use of a tilt lever [5] which will rotate the tumbler and allow the enhanced pet food to be placed into a pet food bag [6]. Any conventional means such as an electronic motor or simple lever can be used to rotate the tumbler [3] for mixing. FIG. 2 also depicts a funnel [7] which while not necessary, helps to improve flow of enhanced pet food from the tumbler [3] into the pet food bag [6]. While FIG. 2 illustrates use of a pet food bag [6] any conventional means for storing the enhanced pet food can be used such as plastic or cardboard containers without effecting the efficiency of the Enhancement Device.

Shown in FIG. 3 are liquid [8] as well as dry [9] enhancer storage containers. Once the OFC has received the customer information, the OFC uses such information to determine the type and amount of specific dry or liquid enhancer to be used. The specific amount of liquid enhancer(s) will then be added to the liquid mixing container [10]. Any conventional method can be used to flow liquid enhancer from the liquid enhancer storage containers [8] to the liquid mixing container [10]. FIG. 4 illustrates that in the Enhancement Device of the present invention, peristaltic pumps [13] are used to flow liquid enhancer from the liquid enhancer storage container through pipes [11] and flexible hosing [12]. A peristaltic pump is a type of positive displacement pump wherein a rotor with a number of rollers, shoes, wipers or lobes are used to compress flexible tubing. As the rotor turns, the part of the tube under compression is pinched closed thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state, fluid flow is induced into the pump. While other conventional types of pumps can be used, a peristaltic pump is used in the Enhancement Device of the present invention because it will eliminate cross contamination of the enhancement liquid with exposed pump components typically found in other forms of positive displacement or rotary pumps. Two or more liquid enhancers can be mixed within the liquid mixing container [10] using any conventional technology such as a magnetic stirrer so long as there is no cross contamination between the mixer components and the liquid enhancers. Liquid enhancers can be maintained at room temperature or heated within the pail heater [14] shown in FIG. 3 . The pail heater utilizes any common heating technology such as an electric hot plate.

The specific amount and type of dry enhancer to be used, as determined by the OFC, is measured and weighed using the digital scale [2]. The kibbles, liquid enhancer and/or dry enhancer, are then placed into the tumbler [3] and rotated for an amount of time sufficient to mix all of the ingredients. If necessary to provide sufficient coating of the kibbles, the liquid enhancers can be sprayed onto the kibbles utilizing any conventional means such as spray nozzles. The enhanced pet food is then emptied from the tumbler [3] using the funnel [7] into the pet food bag [6]. A new nutritional profile is then generated by the OFC based upon the nutritional components of the kibbles and enhancers utilized and attached to the pet food bag [6].

While the preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention as defined in the appended claims.
